Re: [PATCH] scsi/sata write barrier support

Really? That's huge news. Since what kernel version(s) is that?

What about a non-journaled fs, or at least a meta-data-only-journaled fs?
Journaled FS's don't mix well with transaction based databases since they're
basically doing their own journaling anyways.
